FIELD

The present invention relates to a water blocking system for responding to flooding and for guiding water flow in a construction site, in particular, to a water flow guiding structure that is adjustable for uneven ground.

BACKGROUND

Water barrier structures to block water from overflowing into the buildings due to a rainy season or disaster are known. These water barrier structures are intended to prepare for flooding generally occurring in the city, installed on a flat ground such as concrete or asphalt, and typically installed in a relatively narrow range such as a building entrance.

On the other hand, when an initial construction site where digging or piling is in progress is flooded, it is difficult to control and quickly respond to water inflowing from outside or groundwater soaring from underground due to the characteristics of the muddy ground. Therefore, there is a need for a water blocking system that is simply installable and applicable to the muddy ground of a construction site, and can quickly respond to groundwater or external inflow water. In addition, there has been a demand for a water guiding system that can guide the inflowing water to a collecting well in the construction site when the inflow of groundwater is inevitable due to boiling or leakage of piling walls.

In such construction sites, the ground is often uneven and the area to be protected against flooding is wide. Therefore, it is difficult to cope with flooding at the construction site with existing water barrier structures due to wide and irregular ground. Likewise, the existing water barrier structures are not suitable when a waterway needs to be made temporarily on a bare site in a case in which underwater must be guided to the collecting well, for example.

Korean Unexamined Publication No. 10-2020-0068420 (published on Jun. 15, 2019) discloses a water blocking structure adjustable to the floor gradient which has a water shielding wall to be installed in close contact with the uneven ground without a gap. This water shielding wall structure is applicable to the wall of an underground parking lot of an apartment house or a big mart, and is a structure that can be adjusted only for fine curves.

As described above, there has been a demand for a water barrier structure for protecting inundation in a construction site, but the prior art has not been able to propose a solution as in the present invention.

PROBLEM TO BE SOLVED

An object of the present invention is to provide a temporary water blocking system that can be installed on ground in a construction site.

Another object of the present invention is to provide a water blocking system that can be used on all types of on-site grounds such as a curved ground, an uneven ground, and a wet or dry soil ground.

DETAILED DESCRIPTION OF EMBODIMENTS

The embodiments shown in the accompanying drawings are for a clear understanding of the present invention, and the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so they are not described repeatedly unless they are necessary for the understanding of the invention. Although well-known components are briefly described or omitted, they should not be understood as being excluded from the embodiments of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a water shielding plate 10 according to an embodiment of the present invention, which has a protruded portion 12 on one side and a recessed portion 13 on the other side. A width W2 of the recessed portion 13 is set larger than a width W1 of the protruded portion 12. A depth d1 of the protruded portion 12 may correspond to a depth d2 of the recessed portion 13. Referring to (a) of FIG. 1, the water-shielding plate 10 includes a fastening hole 11 a penetrating the protruded portion 12 in the longitudinal direction and fastening holes 11 b penetrating a portion above the recessed portion 13 and a portion below the recessed portion 13 in the longitudinal direction. The fastening hole 11 a, 11 b is formed to have an elongated shape in its transverse section as shown, so that an empty space can be secured in the fastening holes 11 a, 11 b along fastening rods 20 a, 20 b (see FIG. 2) inserted therein. Due to the empty space, the water shielding plates can be spaced apart or inclined in a transverse direction or at an angle after they are connected by a fastening rod.

The height×width×thickness of each water shielding plate may be, for example, 600 mm×500 mm×50 mm, which may be changed according to the installation environment. Aluminum or stainless steel is suitable for the material for the shielding plate. FIG. 1(c) illustrates a water shielding plate 10′ according to another embodiment, which is the same as the embodiment shown in FIG. 1(b) except that the front shape is different.

FIG. 2 illustrates a series of water shielding plates 10 a, 10 b, and 10 c connected each other, with the protruded portion of one water shielding plate 10 b or 10 c being at least partially accommodated into the recessed portion of its adjacent water shielding plate 10 a or 10 b. The adjacent water shielding plates are connected to each other by hammering the fastening rods 20 a, 20 b through the fastening holes 11 a, 11 b (see FIG. 1). In FIG. 2, a portion marked with ‘t’ at the bottom of the fastening rod 20 a is a portion that is stuck on the ground, and it can be more firmly fixed to the ground if this portion is threaded.

FIG. 3 shows that the water shielding plates 10 a and 10 b are installed on the ground G with a level difference. Due to the clearance s formed by the difference in width between the protruded portion 12 of the shielding plate 10 b and the recessed portion 13 of the shielding plate 10 a, the shielding plate 10 b can be positioned lower or higher than the neighboring shielding plate 10 a. In this manner, the bottom side of the water shielding plates can be in close contact with ground with a level difference, and thus, a large gap or mismatch between the shielding plate and the ground which would otherwise be formed can be avoided.

The size of the clearance s is not limited to merely accommodate the protruded portion 12 within the recessed portion 13, but may be determined to be able to sufficiently adjust the height of the water shielding plate according to the level difference of ground (for example, ¼, ⅓, ½, 1, 1.5, or 2 times the width W1 of the protruded portion). As will be described below, the clearance s may be determined to to allow the tilting of the shielding plate according to a slope of the ground (for example, 15°, 30°, or)45°).

In order to set the degree of tilting of the water shielding plate to a desired level, it may be possible to alter the overall shape of the plates, the width or depth of the protruded portion and the recessed portion. Alternatively, it may be possible to configure at least a part of the protruded portion 12, for example, a part that could be contacted by the fastening rod when the shielding plate is displaced from the left and right, with an elastic member such as rubber so that the shielding plate can be tilted more.

FIG. 4 shows that the water shielding plates 10 a, 10 b, and 10 c are installed on an inclined ground G. Each of the shielding plates may be tilted by a certain angle α1 or α2 according to the slope of the ground. In this way, the shielding plates of the present invention can be adjusted to fit to the gradient of the ground.

FIG. 5 is a cross-sectional view illustrating a channel-type water shielding plate structure 100 according to the present invention. A plurality of water shielding plates are fixed to each other and to the ground G by fastening rods 20 so that the water shielding walls 15, 15 are formed on both sides. By disposing side tarpaulins 30 coupled together by a coupling means 32 such as Velcro and a floor tarpaulin 31 coupled to the side tarpaulins 30, 30 inside the water shielding walls 15, 15, a watertight water path, along which water H can flow, is formed. The floor tarpaulin 31 may be coupled to both tarpaulins 30 and 30 by a suitable coupling means 33 such as Velcro. If the distance between the two water shielding walls 15 and 15 is narrow, or the length of the lower portion 30-2 of the side tarpaulin 30 is sufficiently long, the floor tarpaulin 31 may not be used.

FIG. 6 shows the tarpaulins 30 and 30′ according to an embodiment of the present invention. The tarpaulin 30, 30′ is composed of upper part 30-1, 30-1′, lower part 30-2, 30-2′, and extension part 30-3, 30-3′.

The upper parts 30-1 and 30-1′ are to be attached to the shielding plate 10, and may have a width corresponding to the width of a shielding plate 10. As will be described below, an upper part 30-1, 30-1′ of a tarpaulin 30, 30′ may be attached to shielding plates 10 so that it covers respective halves of two adjacent water shielding plates. The lower part 30-2, 30-2′ is to be laid on the ground and may be split along its center line 35, 35′. The extension part 30-3, 30-3′ may include a side extension part 30-3 a or 30-3 b′ formed on one of the left and right edges of the lower part, and a center extension part 30-3 b or 30-3 a′ extended from the center line 35, 35′. The lying direction of the side extension part 30-3 a or 30-3 b′ and the center extension part 30-3 b or 30-3 a′ may be dependent on the flow direction of water. In other words, when the direction of water flow is to the left side, as shown in (a) of FIG. 6, a tarpaulin 30 having an extension part 30-3 a located at the lower left edge and an extension part 30-3 b at the center line 35, with the extension parts 30-3 a, 30-3 b lying on the left side, may be used. When water flows to the right, as shown in (b) of FIG. 6, a tarpaulin 30′ having an extension part 30-3 b′ located at the lower right edge and an extension part 30-3 a′ at the center line 35′, with the extension parts 30-3 b′ and 30-3 a′ lying on the right side, may be used. Since the tarpaulin 30 corresponds to the tarpaulin 30′ when it is turned over, one type of tarpaulin 30 or 30′ can be used for both directions of water flow, with some of them turned over. In this case, coupling means such as Velcro should be provided on both sides of the tarpaulin.

FIG. 7 is a plan view of the water shielding plate structure 100 shown in FIG. 5 with a water shielding wall on one side (i.e., lower side in FIG. 7) is omitted for convenience of explanation.

A plurality of water shielding plates 10 a to 10 d are fixed by fastening rods 20 a to 20 e, and the tarpaulins are coupled to the shielding plates by the coupling means 32. In FIG. 7, the lower parts 30-2 a to 30-2 e of the tarpaulins placed on the ground are shown as rectangular shapes, while the upper parts of the tarpaulins coupled to the shielding plates by the coupling means 32 are indicated as straight lines.

Each one piece of tarpaulin is arranged over two water shielding plates with the center lines 35 a to 35 e of the tarpaulins located at side edges of each water shielding plates 10 a to 10 d (i.e., at the position of each fastening rod 20 a to 20 e) (refer to FIG. 8). By this arrangement, even when the water path needs to be bent, the lower part of the tarpaulin can be in close contact with the ground by being split at its center line, as shown by the lower part 30-2 b in FIG. 7. In such case, the extension parts 30-3 a to 30-3 e extending from the center lines 35 a to 35 e can cover the area opened by the split lower parts to prevent the tarpaulins from being overturned by the water current. In FIG. 7, it is assumed that the water flows to the left side of the drawing, and thus, tarpaulins having the extension parts 30-3 a to 30-3 e lying on the left side were used. Although not shown in FIG. 7 for convenience of explanation, extension parts may be extended to the left edge of the lower part of each tarpaulin to cover the lower part of the neighboring tarpaulin.

FIG. 9 shows a coupling means 32 according to an embodiment of the present invention, where (a) is a plan view of a configuration including water shielding plates 10 b, 10 c and a tarpaulin 30 c attached thereto by the coupling means 32, 32 a, and (b) is a rear view of the tarpaulin 30 c equipped with the coupling means 32, 32 a.

The coupling means 32 may be composed of two Velcro lines 32-1 and 32-3 and a rubber packing line 32-2 between them. When a high water pressure is applied to the Velcro-coupled portion or the water level becomes high, the water-sealing capability of the coupling means could not be sufficient. Thus, the watertight capability may be strengthened by arranging a rubber packing line between the two Velcro coupling lines. Velcro should be provided with a hook on one of the tarpaulin and the water shielding plate and a locking pad on the other of the tarpaulin and the water shielding plate. The rubber packing line may be provided on either side. This Velcro coupling method is suitable for quick and simple installation and removal of the water blocking assembly at construction sites. Of course, it would be possible to apply bolting coupling for more reliable coupling, but it is inferior to the above-described Velcro method in terms of speed and convenience.

FIG. 10 illustrates a fastening rod 20 according to an embodiment of the present invention. The cross section of the fastening rod 20 may be formed differently along its length. That is, when the fastening rod 20 is hammered and sufficiently embedded into the ground, as shown on the right of FIG. 10, the portions corresponding to the fastening holes 11 b (see FIG. 1) that are located above and below the recessed portion of the water shielding plate 10 are formed to have elliptical cross-section, while a portion corresponding to the fastening hole 11 a of the protruded portion (see FIG. 1) is formed to have a circular cross section.

When hammering the fastening rod 20, as shown in (a) on the left side of FIG. 10, the major axis of the elliptical cross section can be placed in parallel with the longitudinal direction x of the elongated fastening hole 11 so that the fastening rod does not be affected by any frictional force during it passes through the fastening holes. When the the fastening rod is sufficiently embedded into the ground, the fastening rod can be rotated so that the major axis of the elliptical cross section is parallel to the transverse direction y of the elongated fastening hole 11, as shown in (b) on the left side of FIG. 10. The body of the fastening rod may be strongly held with a tool and rotated, or a tool may be inserted into a groove (not shown) formed in the head of the fastening rod and rotated. The length of the major axis of the elliptical cross-section of the fastening rod may be equal to or greater than the width g of the fastening hole 11 so that the fastening rod 20 can be firmly fixed with the fastening holes 11 b above and below the recessed portion. On the other hand, the portion corresponding to the fastening hole 11 a of the protruded portion may be formed to have a circular cross section with its diameter being smaller than the width g of the fastening hole 11, as shown in (c) in the left side of FIG. 10, so that the protruded portion can be freely rotated or displaced to the left or right.

By using the fastening rods configured as described above, while one of the neighboring water shielding plates is securely fixed to the ground, the other is displaced up and down, left and right, or at a certain angle so as to contact with the ground as closely as possible. In this manner, the water shielding plates can be connected one by one in a form that they closely contact with the ground.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but those skilled in the art to which the present invention pertains will understand that the embodiments could be implemented in other specific forms without changing the technical gist or essential features of the present invention.
